IMPROVEMENT IN UNDER-BRAlDERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 169,910, dated November16, 1875; application filed March 17, 1375.

specification.

The nature of my invention consists in the construction and arrangementof a braider for sewing-machines, as an improvement on the LettersPatent No. 150,059 granted to me April 21, 1874., as will be hereinaftermore fully set forth.

.Inorder to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a perspective view of my braider. Fig. 2 is a bottom view ofthe grooved plate. Fig. 3 is a section through the line m to, Fig. 1.Fig. 4 is a longitudinal section through the fastening-arm and Fig. 5 isa perspective view of the lever for adjusting the width of thebraid-groove.

A represents a plate of any suitable dimensions, provided on its underside with a longitudinal groove, a, stamped in the plate and forming arib on the upper side. The inner end of this rib is beveled, as shown,and open on top where the braid leaves the groove 61., so as to allowthe needle to strike inside of the end of the plate, and thereby preventit from missing striking the center. On the top of the race a isfastened a spring, I), the loose end of which extends down in the openend of the race a to hold the braid down in front be fore the needlestrikes, and when the needle is raised it prevents the braid fromslipping back when'doing fine work. This spring is of much importance atall times. At the outer end of the race a is a small staple, d, clincheda lever, B, one end of which extends into the race a at the inner end,the race being slotted for that purpose. Within the end of the race a.the edge of the lever is bent downward, forming the braidguide e, asshown in Fig. 5. By means of this combined lever and braid-guide therace is made adjustable for different Widths of braid, and the lever ismade fast at the desired point by means of notches as on the bedplateand a tongue, i, on the lever. At a suitable point on the bed-plate A isa stationary screw, f, with a cone-shaped center, h, to fasten the armOupon, and it being upon a wedge principle, when the nut 70 is screweddown it forms a firm fastening. The arm 0 has. an elongated slot, m,through which the set-screw passes to fasten the arm to the bed-plate ofthe machine, and at one end it has a hole or slot to fit over theconical head h of the screw.

The center of the arm 0 along the slot m is raised, so that the bearingcomes on the edges only, which makes a firmer and 1nore solid fasteningthan a flat plate. The slotted arm 0 gives room to move the braider toor from the feed, and the lever B being adjustable it is very easy tolocate the braider so that the needle will strike the center.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination, with the bed'plate A, provided with the race a andnotches ac a, of the pivoted lever B, provided with the braid-guide eand tongue 1', as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of December, 1874.

VALENTINE LAPHAM.
